Doc Text:
A flaw was found in ImageMagick. A remote attacker could cause a Denial of Service (DoS) through excessive resource consumption by submitting a specially crafted Ultra High Dynamic Range (UHDR) image file. Because the UHDR decoder validates width and height boundaries only after decoding has completed rather than before processing, the application fully decodes oversized images and bypasses configured security policy limits.

Description OSIDB Bzimport 2026-10-25 13:34:39 UTC
ImageMagick before 7.1.2-33 contains a policy bypass vulnerability in the UHDR decoder that allows attackers to evade image width and height limits because extent checks occur after decoding. Attackers can supply crafted UHDR images with oversized dimensions that are fully decoded before policy limits are enforced, causing excessive resource consumption.
